I am assuming that you already had existing Hangame game files prior the service transfer to WeMade Online? The message states, "Patch failed. Please restart the game launcher". Maybe some files got corrupted while updating the game files, your antivirus instantly deleted some files due to false positives, or the patch simply just failed as stated. That error is closely similar to the infamous -7001 error. Sadly, the fix for the -7001 error won't help here.

Right now, there's no official solution found by the SWHQ community, nor the local (Japanese) players. If all else fails, the best option right now, for most, is to re-install the game.

We highly encourage everyone to join our SoulWorker HQ Discord.
Most english players use that to interact with each other and share their game experiences, as well as to disseminate events, updates, etc.IGN: 朝顔
